For adding multicore support. Could make it faster, but needs to be benchmarked.

// @pornel Do you think it's worth using that option? Have you benchmarked it?

It makes serial execution much faster.

I'm unsure about efficiency of running multiple single-core pngquant processes vs multiple multi-core pngquant proceses. The latter shows larger "CPU time" spent, but it may be just because CPU time is bogus with hyperthreading.
